Working Magnetic Motor on you tube??

[Craigy]

Hi All, I ?m sure the vendor said they were n40 , but look more like n42?s to me. Anyway that link above has some nice n35?s. Will have to buy some of those when the missis isn?t looking.

Any way my stator mounting experiment has produced a few observations. First there is no rattle and the rig is practically silent. Second, The stators wll rotate gearwise along with rotor over an enormous speed range. I can stop the stators with the rotor at 1500 rpm and the stators will fire up on their own to go gearwise. So Bearing response , or the lack of it is important..

Hey Craigy,
I have ordered about 5 different sets of magnets, and I can simpathise with you.
All I hear is "not more flaming magnets"

@Any
That spike at the end of the graph is also on the 'no stator' test, does
anybody know the reason for it?

@Omnibus
What grade of bearing did u incorporated into your Stators? I recall u stated "R3", Was curious to what the runout is in the "Y" axis with the single bearing as per the Replication specification in your Rep.

Yes, indeed, the stator bearings are R3 unshielded. Don't understand what you want me to do. If you're curious about the wind down time, it's almost instantaneous. When spinning it by hand it makes 2-3 turns and stops. Let me know if you want me to try something else here.

Hello
No, No test requests from me, Sounds like the bearings are to loose (wobble). I found this with the R3 bearing. The R3 i believe is a ABEC - 1 grade (the lowest). I am switching to a ABEC - 5 or ABEC - 7. I found these bearings at  for  (Grade 7 -$11.57 each) and (Grade 5 - $6.30 each). From what I have reviewed the bearing that Al incorporated had to have been a 5 or better or else the wobble would be in the order of 0.080". This as U know is an important issue with this device. If to much run out the rotor and Stator (AGW) coupling will degrade very very quickly as U are witnessing currently due to the pitching of the bearing. That said I would recommend to look at a better grade of bearing.

Thanks for the reply

Hi Bill,

I ordered my Abec 7's yesterday afternoon.  I pick them up tomorrow from Mike.  They will cost just over $6.00 each.  Ordered for the stators.  They are the best.  I also have him pricing some non magnetic types for us. 

@ All,

Jason's, Hank's and my machined parts were finished today and are now in the mail to us.  We should have them by Thursday or Friday.  I also expect my N35's by then. 

My first attempt will be with the Abec 7 stator bearings, and N35's.  I have high hopes.

Some of you are extremely impatient and I wonder why?  You have invested nothing and are not replicating.  So, if this process takes several weeks or even several months, why should you care? 

I, like Omnibus and others, am in no extreme hurry.  We will work through the variables until we come across the proper combination.

Lastly, I wonder, if all of those magnets that Al had, I think he said 13, were all of the same strength.  He did not know the exact type they were, just that they were "not as strong" as the stator magnets.

@ Rosphere
I got your package today.  Many thanks!   

Cheers,

Bruce

A reminder to the replicators from the original thread.

Seecond, not all magnet/bearing pairs will produce the effect. I have 15 of the magnets, and 13 of the bearings. I have not tried all possible combinations of these, obviously. But of the 13 assembled magnet/bearing pairs, 3 don't seem to work at all, 2 are fairly easy to get started, and the rest are somewhere in between. Even the "easy" ones usually require several tries before successful engagemen

Third, the relative height of the stator and rotor magnets seems important. I don't know if it's because of my particular geometry or whether it is critical to the effect itself, but the magnets shouldn't be in the same plane--that is, I am getting best results when the rotor magnets are rotating in a plane that is just slightly higher than the tops of the stator magnets, rather than down and centered vertically

So, by "working" he understand successful AGW engagement, not so much the appearance of the effect, right? I remained with the impression that the successful AGW latching guarantees the appearance of the effect. What do you think? If that's so I for one am in a good shape, I can achieve AGW quite readily. What remains is to get magnets with the proper magnetic field ratio.
